• 📦 AnyKernel3 Packaging - Ready-to-flash ZIP files
• 🎯 Multiple Build Options - Stock, KernelSU-only, SUSFS-only configurations

Device Compatibility

• Device: Redmi Note 13 Pro 5G
• Codename: garnet
• SoC: SM7435 (Snapdragon 7s Gen 2)
• Android: 13, 14, 15
• Architecture: ARM64

Quick Start

Prerequisites

Arch Linux:

sudo pacman -S base-devel git bc bison flex openssl elfutils zip aarch64-linux-gnu-gcc

Ubuntu/Debian:

sudo apt install git make bc bison flex libssl-dev libelf-dev zip gcc-aarch64-linux-gnu

Clone and Build

# Clone the repository
git clone https://github.com/overspend1/garnet-kernel-builder.git
cd garnet-kernel-builder

# Make executable
chmod +x build_garnet_kernel.sh

# Build with all features (recommended)
./build_garnet_kernel.sh

Build Options

# Full build with Sukisu Ultra + SUSFS (default)
./build_garnet_kernel.sh

# Stock kernel without root features
./build_garnet_kernel.sh --stock

# KernelSU only (no SUSFS)
./build_garnet_kernel.sh --sukisu-only

# SUSFS only (no KernelSU)
./build_garnet_kernel.sh --susfs-only

# Skip AnyKernel3 ZIP creation
./build_garnet_kernel.sh --no-anykernel3

# Show help
./build_garnet_kernel.sh --help

Android NDK Support (Optional)

For optimal Android kernel compilation, use Android NDK:

# Set NDK path
export ANDROID_NDK_HOME=/path/to/android-ndk

# Build with NDK toolchain
./build_garnet_kernel.sh

Output

Build artifacts are created in garnet_kernel_build/output/:

• Image.gz-dtb - Kernel with device tree (for fastboot)
• *.dtb - Individual device tree files
• Garnet-Kernel-SukiSU-SUSFS-YYYYMMDD-HHMM.zip - Flashable ZIP

Installation

Method 1: Custom Recovery (Recommended)

1. Boot into TWRP/custom recovery
2. Flash the generated ZIP file
3. Reboot system

Method 2: Fastboot

fastboot flash boot Image.gz-dtb
fastboot reboot

Post-Installation

1. Install Sukisu Ultra Manager APK
2. Install SUSFS4KSU Module for root hiding
3. Configure root hiding through the manager app

Build Process Details

The script automatically:

1. Dependency Verification - Checks for required build tools
2. Toolchain Setup - Configures ARM64 cross-compilation
3. Repository Management - Clones/updates kernel sources
4. Feature Integration - Applies Sukisu Ultra and SUSFS patches
5. Kernel Configuration - Enables required features
6. Compilation - Parallel build using all CPU cores
7. Package Creation - Generates flashable ZIP files

Advanced Configuration

Kernel Features Enabled

• KPM Support - Kernel Patch Module for Sukisu Ultra
• KALLSYMS - Symbol resolution for KernelSU
• Security Framework - SELinux, LSM, audit support
• Overlay Filesystem - Required for SUSFS
• Namespace Support - Container isolation
• Memory Protection - Hardened security features

Repositories Used

• Kernel: garnet-random/android_kernel_xiaomi_sm7435
• Device Trees: garnet-random/android_kernel_xiaomi_sm7435-devicetrees
• Modules: garnet-random/android_kernel_xiaomi_sm7435-modules
• Sukisu Ultra: SukiSU-Ultra/SukiSU-Ultra
• SUSFS: sidex15/susfs4ksu-module

Troubleshooting

Common Issues

Build Failures:

• Check build.log in kernel directory
• Verify all dependencies are installed
• Ensure sufficient disk space (>10GB)

Missing Cross-Compiler:

# Arch Linux
sudo pacman -S aarch64-linux-gnu-gcc

# Ubuntu/Debian
sudo apt install gcc-aarch64-linux-gnu

Integration Failures:

• Check setup_sukisu.log for Sukisu Ultra errors
• Verify internet connectivity for repository access
• Try manual integration fallback

Build Time

• First Build: 20-40 minutes (downloads repositories)
• Subsequent Builds: 10-20 minutes (incremental)
• Clean Build: 15-30 minutes

Security Notice

This script integrates defensive security tools:

• KernelSU: Provides root access management
• SUSFS: Enables root hiding from detection
• Hardened Configuration: Security-focused kernel options
